Proline Promag 53 MODBUS RS485 Wiring
Endress+Hauser 45
Cable termination in remote version
Promag H
Terminate the signal and coil current cables as shown in the figure below (Detail A).
Fit the fine-wire cores with wire end ferrules (detail B: m = ferrules red, Ø 1.0 mm; n = ferrule white, Ø 0.5 mm)
"
Caution!
When fitting the connectors, pay attention to the following points:
• Signal cable → Make sure that the wire end ferrules do not touch the wire shields on the sensor side!
Minimum distance = 1 mm (exception "GND" = green cable)
• Coil current cable → Insulate one core of the three-core wire at the level of the core reinforcement; you only require two cores for the connection.
• On the sensor side, reverse both cable shields approx. 15 mm over the outer jacket. The strain relief ensures an electrical connection with the connection
housing.
